[tex] \begin{cases} 6x - 2y = 10 \\ x - 2y = - 5 \end{cases}[/tex]
Solve the system of equations by eliminating either x-term or y-term. We will eliminate the y-term as it is faster to solve the equation.To eliminate the y-term, we have to multiply the negative in either the first or second equation so we can get rid of the y-term. I will multiply negative in the second equation.
[tex] \begin{cases} 6x - 2y = 10 \\ - x + 2y = 5 \end{cases}[/tex]
There as we can get rid of the y-term by adding both equations.
[tex](6x - x) + ( - 2y + 2y) = 10 + 5 \\ 5x + 0 = 15 \\ 5x = 15 \\ x = \frac{15}{5} \longrightarrow \frac{ \cancel{15}}{ \cancel{5}} = \frac{3}{1} \\ x = 3[/tex]
Hence, the value of x is 3. But we are not finished yet because we need to find the value of y as well. Therefore, we substitute the value of x in any given equations. I will substitute the value of x in the second equation.
[tex]x - 2y = - 5 \\ 3 - 2y = - 5 \\ 3 + 5 = 2y \\ 8 = 2y \\ \frac{8}{2} = y \\ y = \frac{8}{2} \longrightarrow \frac{ \cancel{8}}{ \cancel{2}} = \frac{4}{1} \\ y = 4[/tex]
Hence, the value of y is 4. Therefore, we can say that when x = 3, y = 4.
Answer Check by substituting both x and y values in both equations.First Equation
[tex]6x - 2y = 10 \\ 6(3) - 2(4) = 10 \\ 18 - 8 = 10 \\ 10 = 10 \longrightarrow \sf{true} \: \green{ \checkmark}[/tex]
Second Equation
[tex]x - 2y = - 5 \\ 3 - 2(4) = - 5 \\ 3 - 8 = - 5 \\ - 5 = - 5 \longrightarrow \sf{true} \: \green{ \checkmark}[/tex]
Hence, both equations are true for x = 3 and y = 4. Therefore, the solution is (3,4)
Answer[tex] \begin{cases} x = 3 \\ y = 4 \end{cases} \\ \sf \underline{Coordinate \: \: Form} \\ (3,4)[/tex]

A company makes two models of television.
Model A has a rectangular screen that measures 44 cm by 32 cm.
Model B has a larger screen with these measurements increased in the ratio 5:4.
Work out the measurements of the larger screen.
Answer:
16/25
Step-by-step explanation:
length of screen B=44*(5/4)=55cm
and its width=32*(5/4)=40cm
so, screen B had dimensions 55cm by 40 cm
screen A area=44*32 cm sqr
screen B area=55*40 cm sqr
so, model A screen area/model B screen area
=(44*32)/(55*40)
=16/25

I need help is this complementary supplementary or nither
Answer:
The answer is supplementary angles.
Step-by-step explanation:
Identify the angle pair as complementary or supplementary.
If one angle is 60 degrees and the other angle is 120 degrees.
First, add the two angles together to find the sum.
60 + 120 = 180
Then, identify which angle pair adds up to 180 degrees.

-100 = -t/5 - 4
please find t! (Explain aswell)
Answer:
[tex]t=480[/tex]
Step-by-step explanation:
Given
[tex]-100 = -\frac{t}{5} - 4[/tex]
Required
Solve for t
[tex]-100 = -\frac{t}{5} - 4[/tex]
Add 4 to both sides
[tex]4-100 = -\frac{t}{5} - 4+4[/tex]
[tex]4-100 = -\frac{t}{5}[/tex]
[tex]-96 = -\frac{t}{5}[/tex]
Multiply both sides by -5
[tex]-5*-96 = -\frac{t}{5} *-5[/tex]
[tex]-5*-96 = t[/tex]
[tex]480 = t[/tex]
[tex]t=480[/tex]

Answer:
0.6
Step-by-step explanation:
Given the trapezoid formula:
1/2(b1+b2/2)xH
We are given the numbers for the trapezoid:
0.3,0.9,1
To solve this here is what we are going to do.
1/2(0.9+0.3)x1
So add 0.9+0.3=1.2
Then Divide 1.2/2=0.6
So multiply 0.6 x 1=0.6
0.6 is your answer

645
Answer:
312
Step-by-step explanation:
25+.15x=71.80
-25 -25
.15x=46.8
46.8/.15
x=312
Answer:
312 miles
Step-by-step explanation:
you have to subtract 25 from 71.80 which equals 46.80
then you have to divide 0.15 from 71.80 which equals 312

What is 5/9 - 3/8?
Here's how to subtract 3/8 from 5/9:
5
9
−
3
8
Step 1
We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.
So we multiply 5 by 8, and get 40.
Then we multiply 3 by 9, and get 27.
Next we give both terms new denominators -- 9 × 8 = 72.
So now our fractions look like this:
40
72
−
27
72
Step 2
Since our denominators match, we can subtract the numerators.
40 − 27 = 13
So the answer is:
13
72
Step 3
Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?

Nope! So now we try the next greatest prime number, 11...
Nope! So now we try the next greatest prime number, 13...
Nope! So now we try the next greatest prime number, 17...
No good. 17 is larger than 13. So we're done reducing.
There you have it! The final answer is:

There are two numbers which sum to 16. If one number is eight less than three times the other, find the numbers.
Answer:
The two numbers are 10 and 6.
Step-by-step explanation:
Let the two numbers be a and b respectively.
Translating the word problem into an algebraic equation, we have;
a + b = 16 .........equation 1
a = 3b - 8 .......equation 2
Substituting eqn 1 into eqn 2, we have
3b - 8 + b = 16
4b = 16 + 8
4b = 24
b = 24/4
b = 6
To find the value of a;
a = 3b - 8
a = 3(6) - 8
a = 18 - 8
a = 10
Therefore, the two numbers are 10 and 6.
2) Simplify: 2a + 3b - 4a + 5c - 2b
Answer:
-2a+b+5c
